Patent number: 5161330Abstract: A side adjustable roller assembly for a sliding door comprises a housing containing a rotatable cam and a wheel carriage with a guide wheel mounted therein pivotally attached to the housing. The assembly is insertable into a recess in the edge of a door, being held therein by a slot in one end of the housing, and by a bend in a strip of spring steel attached to the housing at the other end which engage opposite ends of the recess, respectively. Contact of the cam surface with that of the wheel carriage controls the distance that the carriage can be pivoted into the recess by the door's weight, against the force of an associated spring urging the carriage away from the recess. The point of engagement of the cam surface with the carriage, and therefore the distance between the door's edge and the surface over which it is mounted, depends upon the degree of the cam's rotation, determined by adjustment of cam mounting trunions which can be accessed from the side of the housing.Type: GrantFiled: June 3, 1991Date of Patent: November 10, 1992Assignee: DNS IndustriesInventor: Nicholas A.
